What hydrogen in the atmosphere?

...you do know that water is in the air pretty much everywhere right? And that the H in H2O is... surprise hydrogen...

There is very little water there, and it varies considerably by region. You have to condense it out of the air, which itself takes energy. Then you have to electrolyze it, which also takes a lot of energy. You also can't electrolyze straight water; you'll need a supply of salt.

Once you've worked out all that, why not just feed that power into a regular battery and use that to charge cars? It will be far, far more efficient. Or just build a substation and use the power on the grid.
